ipv6: clean up dev_snmp6 proc entry when we fail to initialize inet6_dev
In ipv6_add_dev, when addrconf_sysctl_register fails, we do not clean up
the dev_snmp6 entry that we have already registered for this device.
Call snmp6_unregister_dev in this case.
Fixes: a317a2f19da7d ("ipv6: fail early when creating netdev named all or default")
